scum.

It is an object of the present invention, to proa burner of this type in which a maximum combustion efilciency may be obtained.

Another object of the invention, is to provide a gas burner, having a burner head provided with a plurality of air outlets, so arranged and constructed that the air issuing from the burner, will pass in cross currents across the path of travel of the combustible gases, issuing from the burner.

Another object of the invention is to provide a burner of this class, so arranged and so constructed that the ratio of air and gas issuin therefrom, may be easily and quickly varied.

Another object of the invention is to provide a burner, so constructed and arranged that the volume of gas consumed may be varied; 7

Another object. of the invention, is to provide a gas burner, having as a part thereof, a combustion chamber so arranged and constructed that it may be'easily removed and replaced with a different size chamber on the same mountings.

Other objects will appear hereinafter.

The invention consists of the various parts and combination thereof, illustrated and described in the specification and in the drawing forming a part thereof in which drawing:

Fig. 1 is a central, vertical, sectional view of the invention.

As shown in the drawing, I provide an air chamber 9 into which air may be delivered through the conduit III by means of a suitable Mounted on the web support is a well ll, tapering from its bottom to its top, the top thereof being of a greater diameter than the bottom and provided with an outwardly flared or inclined lip IS at its upper' end. Mounted on the well I4 are supporting bracket arms l8, which serve as a support for the combustion chamber, these arms I inclining upwardly'and outwardly from their points of attachment to the well I. This combustion chamber comprises an outer shell .l|,'

preferably formed of metal and having an inwardly inclined lower edge 18, adapted to reach upon the supporting bracket arms -Iii, to which the same may be secured by suitable bolts I9. It will be noted that the shell I] as constructed in the form illustrated is a circular band which flares-upwardly so as to extend at an incline to the vertical. ,This band i1 is faced on its inner surface with a layer 20 of fire-clay or other similar refractory material. Its inner surface is fluted to provide the spaced-apart ribs 2|, separated by the channels 22.

Projected through the huh I 2 is a vertically directed gas delivery pipe 23, connected by the elbow 24' to the gas pipe 25 which traverses the housing or. chamber -9 and extends to the exterior thereof, this pipe 25 being connected to a suitablesource of gas supply. The delivery pipe 23 extends above the upper edge of the well I4 and is closed by a plate 26 into thecenter of which is threaded a pipe 21, extending upwardly therefrom and closed at its upper end. A plurality ,oi' openings 28 are formed in the pipe 23 through which the gas delivered may issue. Positioned upon the upperend of the pipe 23, in embracing relation thereto is a hub 29, formed centrally of, and integral with, the disc 30, this disc blower or other blast producing mechanism. On

' the upper wall II, at one end of the air chamber or housing, is a web support, embodying the cir- Il lying above the openings 28 so that the gas issuing from the delivery pipe 23, passes outwardly from the upper surface of the disc 20.

' Formed on the disc 20 and projecting upwardly therefrom, are the spaced tubular projections ll, having an inclined bore 32, formed therein, the larger end thereof being positioned upwardly. A set screw 32' serves to secure the hub 29 in fixed position on the pipe 23. In the form illustrated, the disc 20 is spaced slightly to provide a passage 33, through which air delivered into the lligusing 9, may pass outwardly from the well deflected upwardl and a portion of it will issue from the well i4 while traveling in an upwardly inclined course, the remaining portion being deflected by the disc ill and elected in a horizontal cular hub l2 and the radiating arms I2. plane.

Due to the inclined lip 15, this air will be The tubular projections 3| project through openings 34, formed in a concave disc 35, which is provided with a circular hub (i6 through which the pipe 21 projects, a set screw 38 being provided for securing the disc in fixed position on the pipe 21. Surrounding each of the openings 34, is a flange or sleeve 39 which snugly engages the periphery of the tubular projections .3l. This disc 35 is spaced from the disc 30, with its concave face directed toward the disc 30 so as to deflect the gas passing through the openings 28 in a downwardly turned direction. The disc 35 is spaced from the disc 30 at the perimeter thereof to provide the gas outlet space 40. By

adjusting the disc 35'on the pipe 21 by moving it toward or away from the disc 30, the space 40 may be lessened or increased thus aifording means for regulating the amount of gas issuing from the structure, the area of the openings 28 being normally greater than the area of the space 40.

v A concave disc 4| is provided with hub 42 through which the pipe 21 projects and a set screw 43 serves as a means for securing the disc 4| in fixed relation to the pipe 21. The disc 4| has its concave face directed downwardly toward the disc 3| so that the air passing through the bores 32 will be deflected downwardly. The perimeter of the disc 4| is spaced from the perim- ,eter of the disc 35 to provide a space 44 through which the air may pass. By adjusting the disc 4| on the pipe 21, the space 44 may be regulated to control and regulate the volume of air issu ing through the space 44. Likewise, by adjusting the hub 29, the volume of discharged gas may. be regulated and the space 33 adjusted to regulate the outflow of air at this space. It is thus seen that the current of air passing out of the space 44' is deflected downwardly so as to cross the current of gas and the lower current of air, thus assuring an intimate mixture of air and gas. In the use of the device, suitable pilot lights,

- electric ignition, means or any other apparatus for igniting the gas may be used. A'mixture of gas and air is driven outwardly across the retrace .tory material 20 and it will circle around the ribs 2| and travel through the channels 22, assuring substantially complete combustion. Experience has shown that a burner of this type is quiet, possessed of maximum efficiency and economical of-operation. It will thus be noted that the space between the disk 35 and the cover 3|! forms a gas-receiving chamber. The space between the disk 4| and the disk 35 forms an air-receiving chamber so that there is present in the structure a gas-receiving chamber communicating with the atmosphere by outlet passages through which the gas may flow to the atmosphere. The air-receiving chambers are positioned on opposite sides of the gas-receiving chamber and each has an outlet passage whereby the air may pass therefrom to the atmosphere and there become commingled with the gas issuing from the gas-receiving chamber. There is, of course, present, means for delivering gas to the gas-receiving chamber and another means for delivering air into the air-receiving chambers. I
